The shape is an octagon.
A three-dimensional shape with eight triangular faces is called an octahedron.
A two dimensional shape would have 17 sides. For a three dimensional shape - assuming that sides are faces - the answer depends on the shape itself.
When two sides (called faces) of a 3-dimensional shape meet, they meet at an edge.
That is called a polygon.
A dodecahedron is a three-dimensional shape with 12 pentagonal sides.
A two-dimensional shape with three sides is a triangle. A three-dimensional shape with three faces is a cylinder.
A two-dimension shape with eight sides is an octagon. A three-dimensional object with eight sides is an octahedron.
A three-dimensional shape with eight triangular faces is called an octahedron.
A two dimensional shape would have 17 sides. For a three dimensional shape - assuming that sides are faces - the answer depends on the shape itself.
A shape that has 10 sides (two dimensional) is called a decagon. A shape that has 10 faces (three dimensional) is call a decahedron.
uhh, a triangle?
An octahedron. It has three axis.
A decagon. A two-dimensional shape (plane figure, or polygon) which has ten sides is a decagon. A three-dimensional shape (polyhedron) which has ten sides (plane faces) is a decahedron.
When two sides (called faces) of a 3-dimensional shape meet, they meet at an edge.
That is called a polygon.
2-dimensional shapes, with three straight sides have three vertices.
A dodecahedron is a three-dimensional shape with 12 pentagonal sides.
